refactor: Modularize SQLite native library loading logic

[priyanshsolanki]

• Extracted loading logic into helper methods for better readability and maintainability.
• Added clear and concise comments to explain each method's purpose.
• Ensured consistent error handling and path tracking for failed attempts.
• Improved code structure to make it easier to add new loading strategies in the future.

This refactor does not change the functionality but makes the code more modular
and self-documenting, aligning with best practices for maintainable code.
